I want to ensure that my latest commit has the current date before I push. Since I always rebase to master before a merge + push, I made this alias:

[alias]
    sync = !git commit --amend --date=today && git rebase master

Problem is, it keeps launching my text editor asking for a new commit message. Is there a way to have an optional parameter, so that I can choose to use either:

git sync 'my commit message'

or

git sync

where the latter will simply use the existing commit message, whatever it happens to be?
